1 NFPA 10 Changes & Extinguisher Maintenance Definitions: – Clean agent – Maintenance – 30 day inspections

2 Pressurized Fires – Liquids – Forced – Pumped – Sprayed NFPA 10 Changes & Extinguisher Maintenance

3 1984: – Replace at next 6-year hydrostatic test – Does not apply to wheeled units – Fixed nozzle NFPA 10 Changes & Extinguisher Maintenance

4 Operating Instruction/Identification – Pictographic – Easier to identify – Standardized throughout the industry NFPA 10 Changes & Extinguisher Maintenance

5 Certified personnel – Factory trained – Certified by AHJ – Licensing NFPA 10 Changes & Extinguisher Maintenance

6 Maintenance Procedures: – Physical condition – Mechanical parts – Hoses on wheeled units NFPA 10 Changes & Extinguisher Maintenance

7 Maintenance Procedures – Rechargeable stored pressure dry chemical hand portable extinguishers NFPA 10 Changes & Extinguisher Maintenance

8 After today’s presentation ask yourself Are we using the right fire extinguisher? Will it put out our fires? Are we keeping SAFETY our #1 priority? NFPA 10 Changes & Extinguisher Maintenance

10 Combustible Metals – ease of ignition of thin sections, fine particles, or molten metal NFPA 10 Changes & Extinguisher Maintenance

11 Form of metal affects combustibility Castings, blocks, billets, extrusions, etc. will not react or burn easily Turnings & shavings will react more easily to water & ignition source Powders may react to moist air, burn easily, even explode if airborne The more finely divided, the easier to ignite NFPA 10 Changes & Extinguisher Maintenance

12 Heat from grinding, machining, sparks, or other burning fuels usually causes ignition in these metals Most metals burn at very high temperatures Relative slow progression of fire compared to Class “B” – closer to Class “A” rate Toxic/caustic fumes Once ignited most metals will react violently with water NFPA 10 Changes & Extinguisher Maintenance

13 Other fire considerations Magnesium melts as it burns & may form puddles of molten magnesium – explosion hazards with water Alkali metals react violently with halons Detonation can occur in reaction between potassium and bromine in halons Lithium will burn in nitrogen Lithium fumes are more profuse & dense NFPA 10 Changes & Extinguisher Maintenance

14 Magnesium Chips MET-L-X NFPA 10 Changes & Extinguisher Maintenance

15 Magnesium Chips Water NFPA 10 Changes & Extinguisher Maintenance

16 Sodium Bar MET-L-X NFPA 10 Changes & Extinguisher Maintenance

17 Sodium Bar Water NFPA 10 Changes & Extinguisher Maintenance

18 NFPA Standards: storage, handling, processing - magnesium storage, handling, processing - titanium storage, handling, processing - zirconium combustible metals, metal powders, metal dusts prevention of fire & dust explosions – mfg, processing, handling NFPA Fire Protection Handbook – Latest edition 2008 Material Safety Data Sheets (MSDS) from suppliers of metals NFPA 10 Changes & Extinguisher Maintenance
